Cause

Specifics of product design.

When you rescan multiple media in bulk and some of them are not Acronis media (tapes are either empty or previously used by different software), the following warning is raised for each of such media:

Cannot rescan tape <tape_name> because it is not an Acronis media. Please eject the tape if it contains valuable third-party data or run the erasing operation to be able to use the tape.

If the only media being rescanned is detected to be non-Acronis media, then the rescan operation will fail with Ensure that all the tapes are online and not corrupted .

Product behavior and error message text will be improved in future versions of the product.

Solution

If the tape detected as not Acronis media contains no valuable data, erase the tape to be able to use it with Acronis and then rescan the tape again.
